rtl_433 no longer receives messages

Hi there, hope someone can help me.... you can answer to me in English or German...

I used rtl_433 (version 18.12-262-g74b9a82) a few weeks an a Raspberry Pi3.

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" NAME="Raspbian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian HOME_URL="http://www.raspbian.org/" SUPPORT_URL="http://www.raspbian.org/RaspbianForums" BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

since two days I get any messages, when I start the program.

Use -G for testing only. Enable protocols with -R if you really need them.

Consider using "-M newmodel" to transition to new model keys. This will become the default someday.
A table of changes and discussion is at https://github.com/merbanan/rtl_433/pull/986.

Registered 128 out of 134 device decoding protocols [ 1-4 6-8 10-17 19-26 29-64 67-134 ] Found Fitipower FC0012 tuner Exact sample rate is: 250000.000414 Hz Sample rate set to 250000 S/s. Tuner gain set to Auto. Tuned to 433.920MHz. Allocating 15 zero-copy buffers

after a minute or two I get this message:

pulse_FSK_detect(): Maximum number of pulses reached!

What does this message means ???

I know this dongle is not the best, but it worked a few weeks 24/7 the only problem with this device was it hangs up sometimes.... I get this message when it hungs up.

Async read stalled, exiting!

Question: what USB donges do you use with good Experience ?

I checked the USB DVB-T stick on a Win 7 computer using rtl_433, with the same result. My first idea was that the reciever is broken, but with a SDR software it seems to work. I also have a RTL.SDR.COM V.3 Device and tried this with rtl_433 (the RTL.SDR.COM V.3 works with a SDR software too)

I also tried with the RTL-SDR.com V3 hrere the result:

Use -G for testing only. Enable protocols with -R if you really need them.

Registered 128 out of 134 device decoding protocols [ 1-4 6-8 10-17 19-26 29-64 67-134 ] Found Rafael Micro R820T tuner Exact sample rate is: 250000.000414 Hz [R82XX] PLL not locked! Sample rate set to 250000 S/s. Tuner gain set to Auto. Tuned to 433.920MHz. Allocating 15 zero-copy buffers

after 2-3 Minutes I get the same message:

pulse_FSK_detect(): Maximum number of pulses reached!

So I tried also with different 433 MHz antennas, so it isn't an antenna issue. Does anyone have a good idea, what the problem could be ? I think two broken devices are unlikely.... What options Do I have, to analize whats wrong ?

Kind regards, Daniel
